Nevertheless, I think the installer is a special case, if only because it is 
the first stop before one has a usable TL installation. The original motivation 
for the thread was that the error message from the installer was very 
misleading as to the underlying cause of the problem. Once a user's attention 
is drawn to checking the Cygwin prerequisites, the user's view changes.

I think I agree with Reinhard that since the installer needs actual cygwin 
binaries for wget and/or curl (and I think others), it would be useful for it 
to restrict PATH to the relevant directories. (And a warning message to the 
console would be useful.)
